An evidence of electron donor behavior of single-walled carbon nanotube in photo-induced electron transfer
The electron transfer reaction between C60 and SWCNTs in D2O was investigated. Repeated laser irradiation of water-soluble C60 encapsulated in γ-cyclodextrin and SWCNTs with carboxymethylcellulose dispersed in D2O resulted in the accumulation of C60 anion radicals and a decrease in the E11 absorption band of SWCNTs, strongly suggesting electron transfer between C60 and SWCNTs. Transient absorption techniques revealed that this electron transfer occurred through the excited triplet of C60.
